Minoura makes a good product, but so does Cycle Ops. So either brand is good. I had the one that puts the pressure on the rims (your second choice) when I first started biking. I liked it a lot because it didn't wear out my tires and I could put the mountain bike with the knobby tires on the trainer without changing out the back tire to a slick. It was also very easy to get my bike on and off of it.
When I started to do 1+ hour rides on the trainer I finally had to go to something more heavy duty.
If you think you might work up to longer rides and don't want to have to replace the trainer, go for the Cycle Ops unit. They have a reputation for being bombproof. (I've never owned one though.)
The first one seems expensive for what you get.
