Help about home trainer

Hello. I am going to buy an home trainer to use durino winter to be' a little prepared to cycle for spring. I am planning to train legs after some years stop. Staying on budget i was planning i saw these three trainers.
- Tacx i flow t2250 little used for 250€
- Tacx genius multiplayer used for 320€
- Bkool one new for 270€
Considering i am not interested to have a videogame, but a valid trainer to do what i wrote, some one could give some advises to choose one of these?
All ideas are welcome.
Thanks,
Roberto

Re:

Save your money, buy a cheap mag trainer that is all you need. Hardest part is getting on it next hardest is staying on it.

I do 50 minutes a day on my trainer having worked up from 20 minutes every other day 22 months ago. Best investment is something to draw your attention, I invaribly use my current favourite bike as my focal point, stood right in front of me and before I know it I have done my 50 minutes (usually 500+ calories according to my Heart Rate monitor).

I use my trainer outdoors, dodging rain when necessary. If it rains all day on my days off or after my work shift it is a bona fide day off I never start a session in the rain but often finish in it :|

I upload my results to polarpersonaltrainer.com, having just checked I have covered 1560.2 miles taking 131.9 hours burning 70938kcal from 170 sessions since the 10th May 2015. This doesnt include my none turbo trainer cycling...

70s Disco music helps me, keeps my cadence up.
