It looks like you bought at about $150 per thousand points, which isn't that bad for retail price. My advice would be to see if you would be interested in becoming VIP Gold since you're stuck with it unless you default. All of my points are resale and I don't see buying two 3 bedroom PICs to get to VIP gold as a bad financial decision if you can afford it. I'm personally going to probably buy a bit of DVC and Worldmark for 1-2 night stays, so I don't need Gold benefits, which is why I'm resale only. But once you see how housekeeping credits and reservation transactions work, you will see how VIP Gold can save money in the long run (after 15 years of use), especially for weekend getaways.
To get permanent VIP Gold, it will cost you an additional 166,000 points when they bump up the requirement to 800,000 points. You can get the PIC deeds for free from timeshare nation that will give you an extra 508,000 points for VERY low maintenance fees. If you call telesales, you can buy 168,000 points from them (exactly 166,000 isn't sold) for $134 per thousand. Permanent VIP Gold will cost you an extra $22,512, but it's worth the $41,000 price tag if you properly use it.
Developer points aren't worth their price tag unless you plan on being VIP. There's very little difference between retail and resale when you own less than 400,000 points.
