I'm in a similar position. I've spent a lot of time crunching the numbers (for myself), and generally speaking, the best "sweet spot" between points and membership fees is a 7000 point contract at Vegas Strip or Paradise, followed by Flamingo and then some of the lower-fee Orlando properties.
If you're looking for more than 7000 points, it might make sense to buy two 4800 point weeks. There are 8400 point and higher contracts that have low membership fees in Vegas, but it seems that they don't come on the market very frequently, and when they do, the asking prices are pretty high. If you can get a good price on two 4800 point units, at properties with low membership fees, you can get 9600 points, and the two membership fees combined aren't that much higher (or might be lower) than a single deed point package in Hawaii, where higher-point weeks on a single deed are easier to find --but you have to really crunch the numbers and find a really good deal.
I'd stay away from the gold week one bedrooms, though--for the same membership fee, you can get a 4800 point package at the same property.
