Ah that's something good to bring up....I'm 6'1" so I need to see if I'll fit in a -4. I've heard they are a close fit.
My budget cap would probably be about $45,000. I would use it to commute to and from work. Right now I commute via "plane pool" with a fellow employee in their Lancair 320. It's the perfect plane for it. It's about a 25 minute flight each way. In the end with split costs of fuel, its about 100 bucks a week. Not too shabby. Of course that doesn't count all the other operational expenditures but since it's experimental its easier on the maintenance costs. But Lancair's, even the 230, aren't cheap to come by. Ultimately I want something fast, economical, and fun. I'd love to buy a Pitts S-1, it's easily attainable and high on the fun scale and I could race it in Reno, but low on the economical scale and in between in fast the fast scale. So I've had quite a few people talk about the RV-4. In the starting research I've done so far, it's pretty good all around in speed, economics, and fun. I'm not Mr. Moneybags quite yet so I've got to be a realist and look for the best combination that will fit me best.
