Stuart,

Unless you absolutely want the experience of building, you may (I don't
know the situation in Australia) be able to find a used mobile 2m or
2m/70cm tranceiver for a reasonable price. My used Yaesu FT-2800M cost
me 100 Canadian dollars. I had been thinking of buying an amp for my HT
but discovered it is easier to simply buy a transceiver that gives me 25
watts along with 3 other power choices.

This is the ultimate aim... will be to purchase a newer radio. I have
my eyes set on a FT-897D, but it'll require quite some saving to
acquire the necessary cash.

I would still like to homebrew a linear amp though, as the final stage
for homebrew transceivers. This would be something that I'd be
looking to do in order to improve my understanding of
radiocommunications.

I'm also aware that I need not use a linear amp for FM (or CW/PSK,
class-C amps work for these modes), but since the homebrewing
mentioned above may also include AM and SSB, I figure a linear is
going to give me much better flexibility.
