if it helps put your mind at ease, I do own a boaphile ballroom rack and I did not receive any confirmation of my order. I did call jeff twice during the six week waiting period, and each time he picked up and assured me that my order had been processed. like you I worried about the lack of any confirmation email (other than paypal telling me I'd sent the funds), but boaphile just appears to be one of those companies from which you have to accept a certain amount of ambiguity.
I would gladly purchase from them again, and I have absolutely no complaints other than the lead time. indeed I think they sell some of the best cages on the market (although I am looking to purchase all my future racks from RBI due to the comparable quality, reduced wait time, and excellent customer service). jeff from boaphile is certainly no scammer, and the products speak for themselves. unfortunately you might have to deal with little to no email communication. however if you call them, you should undoubtedly expect at least a call back or an in-person verification.
either way, I wouldn't lose any sleep over it. what exactly did you order? please do post a thread when you get the product.
