I have no experience with Race Technology, but I have a Racepak G2X that I bought for a similar reason - the hardware is great for the price. Sort of the same thing with RT, as far as I can tell, their hardware seems fantastic for the prices they charge.
My conclusion is that the hardware is the least important aspect of data analysis.. It's all about the software and the support that you get with your product. And really, the reason most bigger data companies are so expensive, is they sell a niche product to a very small market, but still need to maintain a staff of highly skilled people to support the product and develop the software, etc. Smaller companies (definitely looks like the case with Racepak..) outsource their software and are very slow to release updates or fixes. The support staff can be stretched thin - takes me about a week to get an email reply from Racepak. And even if I reply straight back, it usually takes another week to hear back from them again.
If I knew what I know now, I would have bought an AIM system. They're still relatively affordable and the support (and the number of ways you can get support) is a lot better. Plenty of people with TONS of experience and knowledge about AIM's race studio, including John Block's great classes.
Anyway, it all depends on how deep you want to go with this. Driving an FV, I wouldn't go crazy on a data system.. There's only so much you can do with a vee as far as setup (and hence analysis of the results..) goes. The only reason I'm still spending money with my data logger is I seriously enjoy playing with the data and figuring out new ways to look at it. But I consider data analysis a side hobby, not just a tool to help with my Vee. It certainly does help, but I'm way past the point of diminishing returns..
