The Marlin will probably set you back a lot more than $700 these days, and while I loved my Marlin 1894s and my current Interarms M92 in 357, I'd suggest a good 22RF rifle. Lots of options out there for less than $700 and ammo is still a lot cheaper than factory CF or reloading costs.
Get a good used Marlin 39A with a receiver sight that will supply tons of shooting fun and never look back.
