I'm with McG-of-H: if you can play violin, you will certainly be able to play as much guitar as you want to!

Unfortunately, a cheap guitar can be much more difficult to play (i.e, more painful to finger) than a really good one -- makes it problematic to start trying to play before you're ready to make a serious commitment. Borrowing (or renting) a decent instrument might be the way to go before making a sizeable investment.

I would advise against getting a nylon-string classical-type guitar as a "starter-kit" unless you plan to keep playing that type of instrument (which is a valid option, of course). If you figure you'll eventually want to play steel-string acoustic, don't put yourself through a transition, just start out with a steel-string 9perhaps using ultra-light strings for starters).
