I'd have to agree with the previous comments, with a couple of observations of my own, FWIW.
I own a couple of Maks: a Bulgarian and a "commercial" Russian with the huge adjustable rear sight. Both were inexpensive, generally well-made, and surprisingly accurate. Both have been 100% functionaly reliable with a variety of ammo.
The front sights are tiny, shiney and hard for my bifocal-clad eyes to pick up quickly. Out-of-the-box actions were stiff and a little gritty-feeling. I'm not a fan of the heel-type mag release, but it's perfectly usable with practice.
But for under $150 in new condition, it's cheap enough to warrant a little judicious fiddling. Ammo is cheap enough to "shoot it smooth", if you're not handy. A thousand rounds of use makes a dramatic difference in the action's feel. Makarov.com has detailed instructions for a DIY action job. The mechanism is simple and robust, so with a little patience and careful polishing it's not hard to get very nice results for just the cost of materials.
Sights are another matter. For younger eyes a little colored enamel on the rear face of the front sight might be all you need. Novaks or XS sight sets in several variations are available, but they're not cheap (even at their most basic) and proper installation isn't a "kitchen table" job. It cost me $120 to have a set of XS "standard dot" express sights installed on my Bulgarian's slide, including return shipping. Value is relative, but the results in terms of improved practical accuracy and speed are amazing.
The CZ 83 doesn't need any of the above. But it's even larger relative to the power of the cartridge, and around here a nice used one will fetch a considerable amount more than I have in my Mak with the new sights factored in. For those of us in the USA, the difference in mag capacity is two rounds unless you can afford the scarce and expensive high-caps. Again, value is relative. With a "marginal" caliber it is arguable that more is always better. IMHO, if I have any doubt about my ability to solve my problem by placing eight rounds of the best available SD ammo into the COM, then I need another caliber more than another two rounds.
Here's where I'm with Walt: if I can get the same number of 9x19s or .40 S&Ws in a weapon of the same relative size and weight for the same money as the 83, I'll take it instead. Subjectively, the difference in recoil between a locked-breech 9x19 and a blow-back 9x18 in a twenty-odd oz. pistol is neglibable to me. For tight budgets, the little Keltec P11 goes for about $230 in these parts. Mine has been absolutely reliable and quite accurate. Okay, the looong DAO trigger pull takes some getting used to, and the grip is a bit boxy, but you've got much more oomph in the package.
