You might want to take into consideration what the cost of owning a rig is also if you only plan on about 30 jumps/year. If you figure 3 reserve re-packs at around $50 each, the cost of a cypress at around $170/year and if you pay someone to pack at about $5/packjob it may not cost you much more to rent for awhile. I plan on jumping around 50 times/year and decided to get my own rig mainly to get over the psychological barrier of paying $20/jump for rental. I figured with my own gear I'd be more willing to jump cause it'd feel like I was spending less. In reality it'll probably cost me about the same/jump when all is said and done. The point is you don't need to be in a big hurry to buy something.
