Which paint spray gun to buy?

[Birdman]

My in-laws gave me some cash for some air tools for my birthday. I want to get a good spray gun so I can spray some primer and paint on the car. I have a smaller air compressor that can keep up with a paint gun, but I want something that doesn't tax it too much.

I found an HVLP gun that I really like, but there is also a siphon feed one that is pretty nice there, too.

Which one do you guys think I should go with? I'm pretty new to using an HVLP gun, but I used a siphon feed a while back on my truck.

I want to buy them in the next few days, what do you guys think would be the best option?
