Having returned to vinyl this year I've been mostly on Techiepedia, so I guess you might not know me here. Hello from Nottingham.

I've been enjoying making compilation cassettes of favourite LP tracks, sequenced in DAW, output through Presonus Central Station.
I'm interested in better sound quality than my Denon720R compact cassette, so I've begun considering RTR.

Would I be better looking for a two track model, or is four track good enough for what I'm doing?
Is 7.5ips an appropriate speed, or would I gain anything from 15ips?
Which machines are proven to be reliable, with servicing and spares available in UK. Around the £400-500 kind of level?

Thanks for looking at my newbie level questions, we all have to start somewhere!
