Can't say anything about clays....but vector lab kit is pretty awesome. I am a self declared electronic idiot and it was simple to install the vector labs kit onto my sw pcb. And game play is awesome. Easy to switch between games. You can either use the thumb buttons on the yoke..or there is a wire that can be used to switch between games manually. I will not be getting rid of this pcb set!
I've got one of Clay's older kits. Installation is a little bit of a PITA by comparison to the vectorlabs but when running is every bit as good as you'd expect it to be.
Pro's:
- no mods in software (well that is a pro if you are a purist....)
- easy to install
- works reliable
Cons:
- wire between three boards is flimsy, I had to resolder it 1 or 2 times while working on board-sets.
- switching between games can take several button presses
- no software mods (well that is a con if you want more comfort...)
