Suggested source for new prop?

[YankeeClipper]

Front propeller is a threaded-type in need of an overhaul, and IA says I should consider replacing with a new, (flange-type?) instead. Is this as simple as going to airpower inc and putting my 15k down and moving on, or are there options I should be looking into?

With respect to 3-blade: I'd love nothing more, but the only reading I've found says no mixing with a 2-blade, and I just don't have the budget for a second one (the rear blade is just fine). Also, I'm guessing that Aviation Enterprises is out of business--or on hiatus--anyway, because no amount of phone calls and messages has earned me a response.
