Hi Juan,
You didn't mention specific frequencies, so I assume 2M and 70 cm.
Building appears to be the way to go, if you can. I'd probably use the Mitsubishi H2/H2S series of bricks. They come in various power levels up to about 60 watts with the drive requirements you're looking for.
See RF Parts www.rfparts.com and select the power module section.
For interfacing, check out Jim, W6PQL's boards.

Scroll down to the MosFet Module Amplifier kit.
