How about one of these modules?
http://www.bkelec.com/DIY.htm
I have one of their old bipolar transistor ones here that my brother built
into a sub. It's been running on and off (depending on who could find room
for it at the time...) for years! £43-85 incl vat for 100w with a
built in power supply can't be bad.

Bloody hell, those modules have been around for YEARS, haven't they?!

Specs look a bit... well, for example, the 100W nominal one claims
105W into 8 Ohms (fair enough), but only 115W into 4 Ohms. Krell it
ain't.

Worse yet, the amp marketed as 1000W is positively cheeky:

8 Ohms: 550W -- HUH? I thought this was meant to be 1000W Cheeky gits.
4 Ohms: 725W
2 Ohms: 1050W

Even quartering the load resistance, you get less than a doubling of
supplied power.

Still, they're cheap so you can't really complain, but I think that given that
their 100W amp really does deliver 105W into 8 Ohms, it's a ****ing cheek
that you only get 550W from the "1000W" amp, and you need to go down to 2 Ohms
to get your 1000W!
