I guess it's all relative...

Grip-n-pull = $40 and fits a handful of bullet diameters
Hammer type = ~$20-25 for effectively any cartridge (suck for lightweight bullets)
Hornady/RCBS/Forster collet type = $20-25 for the "die" + $10-12 per cartridge
RCBS Adjustable Collet puller = $125

So the hammer type is the cheapest option. Grip-n-pull is the second cheapest option, really, unless you only reload one caliber, where it effectively breaks even against a collet puller. Wanna pull 9 different calibers and don't care if you ruin bullets? The Hammer is $20, the GNP is $40, and the Collet types are $135...

I tend to think if you only have ONE, it should be a hammer type. Small caliber bullets suck on any of them, as they don't have much exposed bearing surface for gripping, and don't have much inertia to overcome the neck tension. With enough whacking, the hammer will get it. If the bullet grippers can't get a grip, they can't. But really, it's d@mned nice to have both options.

ETA: The grip-n-pull works fine - but you do need a means to hold the cartridge case securely. I use a Lee cartridge holder for their case trimming gear and T handled lock stud I made.
