Which exercise bike to buy?

I'll soon be 3 months post THR. My ultimate goal is to get back on my e-bike but I need to start on a static bike. Can anyone recommend an upright bike, not too expensive, that I can get onto easily. I tried one at the local gym but needed to get my hip above 90 degrees to get onto it. In any case, I'm not going back to the gym until this Covid wave is over.
