Buying a razor from SRD is a no brainer and you will never be sorry you did. Besides you will get a razor honed by Lynn!
As for which one, they are all good Dovos and will perform about the same. Go with what you like best.
I really like tortoise faux ir not. Be aware that the gold wash on the spine and tang will probably wear away over time if you use the razor in on a regular basis. Check out the DD Goldedges and others on EBay and see what time has done to those. The gold wash does look really sharp while it is on though.
Good luck. Let us know what you pick!
