If you want to go carbide, take a look at the prices of inserts in
real tool suppliers catalogs, rather than the folk that supply the
hobbiests, and sort out what you can use from there.
One or two good quality holders can make your hobby that much more
relaxing, while a bunch of affordable garbage will like to make you look
for a new hobby.
That said, the shop I work in sprung for a set of "TMX" branded
(pretty close to the quality level of the Glanze stuff I have seen in
the adverts, I think)turning tools that use the CCMT inserts, and they
seem a reasonable quality for the price. I have no doubt that the screws
will have to be replaced sooner than if they were of good quality, but
even the top quality ones suggest that the screw is chucked and replaced
every few insert changes.
See if you can get on the mailing lists for a catalog or two from a
proper tool supplier. Buy a catalog or two if you must. The information
is gold!
You could also consider making your own holders for some of the
cheaper triangilar inserts.
IMO if you were really impressed with the carbide toolings cutting
performance, you should work on your HSS grinding skills. HSS is cheap,
and can be rapidly changed to adapt tothe different materials as
required, while carbide can be a drain on the fiscal resorces, if one is
having a bad day.
A couple carbide end mills are handy to have around for getting past
something miserable, but unless you are able to drive them hard and on a
rigid machine, you would be better off spending the money on quality HSS
end mills. They are WAY more forgiving when being run through material
by hand crank, rather than power feeds.

Wally,
Its horses for courses, I have Clarke lathe and use High Speed Steel if I
want a shaped tool i.e large radii or thread cutting, if I want to rip metal
off in a hurry I use braised carbide tips or throw away tipped tools. You
will need a green wheel to keep the braised tips sharp and I use a diamond
hone or file to keep an edge on the throw aways. Like most things if you
take your time the tools will last.

Please log in for more thread options Thanks, all, for the many responses. This has made me think more about the
tools I reckon I'm most likely to use, and I'm now convinced that choosing
the individual tools is the way to go. I had been looking at the sets and
wondering how much value they really were - how many tools for free,
effectively - but I struggled to find enough tools in the set that I'd buy
individually to equal the cost of the set and thus score the freebies. But
there's no 60deg threading tool, the chamfering tool only does 45deg one
way, etc.
Turns out that the main LH and RH cutters and the boring bar are all I'm
really interested in from the set. The ones with the narrower inserts look
interesting, and I may get one or two of those with small radius tips.
Not sure what to do about threading - I don't really do screwcutting, but I
can foresee a need for M14 x 1mm CW and ACW threads, inside and outside,
10-12mm thread length. There are some threading tools on Chronos (click the
photo of the blue box for a close-up of the tools)...
http://www.chronos.ltd.uk/acatalog/New_Glanze_Indexable_Threading___Parting___Profiling_Sets.html
Too big for my lathe at 10mm, but the type looks interesting to my
inexperienced eye. Are they any good? Also, what's the profiling tool for?
Is it for doing left/right cuts while plunging into the side of a shaft,
before finishing the inside corners? Can it be used for anything else?
On milling cutters, point taken re carbide tools on a small manual machine -
I'll look at HSS.
