Rentals are usually available at piano stores,, but this all depends on the store of course.... typically starting at $25 a month for a real used-up upright... it goes up from there..... if you're in the market of digital pianos,, I'd just suggest you get a second hand (or new if you have the money) from either online,, or music store.
Typically a good digital piano with realistic touch, will run you about $600-$2,200 for a new model,, and a few hundred less for a second hand unit..(price reflects digital piano keyboards, not digital pianos that look like actual upright pianos, those will cost much more)
example: New Roland (RD-300sx) will run you about $1,400. One step higher (RD-700sx high-end digital) will be right around $2,000. But you can find the first generation RD series keyboards from roland (RD-170) on ebay for around $350-$700.
look into makes like Roland, Korg, and Yamaha... they have a pretty strong line of digital pianos, most are even giggable (another term for being portable).
As far as your concern with the touch difference.... to be honest,, nothing today will duplicate the realistic touch of an acoustic piano,, however, most come close.. -- but to answer you question:
yes it should be good enough.
