Cheap tents fail. some of the Eureka are OK though.. That solitaire is more like a very roomy bivy and it doesn't breathe too well. I think the spitfire might be OK.
It's pricey, but it's light and it's one of the go to solo tents. http://www.amazon.com/MSR-05143-Hubba-Tent/dp/B00414IWA6/ref=sr_1_13?s=sporting-goods&ie=UTF8&qid=1386557672&sr=1-13&keywords=solo+tent
Once you get out there and start using your gear a lot, you will see what the more pricey stuff has to offer. Start off with something super cheap. If you want to keep doing it, buy something nicer. I wouldnt spent $70 on a solitaire.. you will most certainly want to upgrade.
I'm a hammock guy myself. I've spent many many nights in a tent. I started out with a cheap tent, then bought a really nice once.. The nice tents hold up better, less condensation and don't leak.
Then I tried hammocking(3 years ago) and never went back to a tent. A hammock and tarp is the way to go IMO. You are about to jump into a rabbit hole if you wanting info on all this stuff. hammockforums.com
