As many others have said you'll either love it or hate it..
It realy matters if you have extraction problems with yours..
The 940s are a real power house & some brass just doesn't want to work well with it while others are just great.. You'll have to experiment with variouse brands & bullet weights to get the perfect round for your needs.. My main trouble with my 940 has been with Winchester White Box 100 round value packs that I use as plinking ammo for other 9mms
My 940 had one of the worst looking chambers I've ever seen but still would shoot & extract most loads except for the WWB..
I first honed the cylinder with the brownells flex hones & later had the chamber reamed to accept the longer 38 Super & still can shoot the 9mm as the cartridge headspaces on the moon clips..
BTW I have two sets of the 9mm Flex Hones & have sent many 940 owners these hones & cured thier extraction problems for just the S&H
In fact one of the sets of hones is currently with another forum member now.. They do work very well.. My email is at the bottom of post if you need them..
$650 isn't too far out of line on the cost of a 940 nowdays, $550-$750 is a good range for what they have been selling for on GunBroker..
You gotta figure that the 940 no dash came out in 1991 & now are 17-19 years old & are discontinued making them worth much more than a 640.. The Blue book of gun values lists a 940 in 100% condition to be priced at $450.. We all know that this is only a guide..
There's also been several members ream thier 38/357 chambers to 9mm para with great success, I aquired a 940-1 cylinder from safearm & fitted it to my 642 Airweight creating a copy of the experimental one off Model 942..
You need to shoot the beast & experiment with several different bullets to get what works for yours..
Also take an eye loupe & look into each chamber back lit & if there's any ridges in there the honeing may help..See Pics..
Here's what a rough 940 chamber looks like
