Re:Deep fryer advice
I would steer away from Imperial and especially any brand of light duty equipment. With what you're looking to pay you might have to find a deal on some new equipment but I'm sure some digging will pay off. Dean/Frymaster, Vulcans, Pitco, etc. are all stand up products. Pressure Fryers are the bees knees (Henny Penny, etc.) Especially if you're looking to pump out raw to cooked wings with a quickness.
As for review sites I haven't really seen many. Might not hurt to drop by a Buffalo Wild Wings (or whatever comparable venue you might have locally) to see what they use and what they think. Might be able to buy the KM a beer and pick his brain. I'm sure they'll have some input on what works and doesn't (and why they use the fryers they do).
Cheers and good luck!!!
