Jon:
While I haven't played either, I'll give you my $0.02:
For the price, I don't think you can go wrong with the Reeves stuff. They sell direct and have a nice warrantee. Hand-built with hi-quality components just like the originals. They've gotten rave reviews on Harmony-Central.
As long as you like the Hiwatt sound...I call it the anti-Marshall sound, LOL!...you're in good shape. I believe the TOL 100W head they sell is the PT Signature version. Just remember, they're clean amps (unless you REALLY crank 'em up) that you have to ADD distortion to. That's why Gilmour likes 'em...loud and clean with tone, just add effects. Just keep in mind you'll need the matching marine-grade plywood cabs with 12 Fane speakers for that magic sound (i.e., just like a Plexi needs Greenbacks for the other magic sound, LOL!).
Personally, I'm with Bill TGO here: GP is the Stereo Review of the guitar set...never met a product they didn't like, LOL! I'd be willing to bet that Fernandes's Hiwatts are probably as close to a vintage Dave Reeves Sound City/Hiwatt as those Marshall re-issues are to a real vintage Plexi...which is to say not very.
Good Luck in your quest.
Cheers,
Kevin
