You're going to find that the 30-30 will be alot eaiser and cheaper to find new or used, most pistol caliber lever guns are hard to find at a reasonable price new.
You will find plenty of 336 Marlins and 94 Winchesters in 30-30 and some other calibers as 35 Remington and 32 Winchester special.
The older pistol calibers 32-20,38-40,44-40, will bring a premium because of collector value,modern pistol calibers .357 magnum-38 Special,45 Colt ,are sucked up as quick as they can be produced, and they are priced accordingly.
The Italian clones bring a premium price close to the modern Winchesters and Marlins.
The newest"Remlins" are of questionable quality driving the price up on the used Marlins even the crossbolt saftey guns, although recently Remington manufactured Marlin lever guns have undergone a strict quality control effort before leaving the factory.
The newest Braztec Rossi 92's have had good reveiws,but you need to be a tinkerer if you expect to get these guns up and running reliably,a plus is the under 500 buck price tag, if you can find one.
The older Interarm Rossi-Pumas are Brazillian manufactured,the newer Pumas are by Chiappa an Italian company,price on those have gone up too.
