There are several multi-page discussions w/pics of the various mfg's and variations of the conversion units on this forum.
[Search!] 
I don't own one but do read any thread that pops up, and they seem to go for ~$450 - ~$600 on GB & eBay. Even the incomplete ones list at the lower price; wooden box doesn't really seem to affect value unless an actual military-issue box with accessories.
The ERMA unit seems to be most common; the Lothar-Walther next. The Metric caliber doesn't have much following here [4mm?], the sub-caliber ammunition must be hard to find even on The Continent.
The longer K98 conversions pop up occasionally for higher prices.
