I've been in a 21RC 260 merc combo like this and it rode fine, but thats not exactly what I'd call big power As far as the interior, you don't have to take it to Schiada to get one one. Franky here on the boards looks like he got a screamin deal on a "Schiada looking" interior out in Havasu, I know Stitchcraft has done their stuff in the past, as has Stratton interiors. So you don't have to take the boat to Schida to get some new vinyl in her.
As far as V'drive cruisers.... small market, low volume = big margin There was a vector on here not that long ago that I thought was a freaking steal. I'll see if I can find it and post it up on this thread for you.

Edit:
Goodtime$,
Here is the thread about the Vector for 23k http://www2.***boat.com/forums/showthread.php?t=75749 Seems like a good deal from the pics. You might try PMing boat124 or Jrocket since he posted it up.
Good luck
