The bottom line is, its probably worth 29 bux. I had one 5 years ago or so, the biggest factor here is the price. If it was 100 bux, that would be different.
Any of those starved plate pres sound horrible anyway when the tube is driven, but some sound pretty good for the money as just a pre, or as mentioned, DI. Good example is the VTB-1..... I still have one, aND I wont sell it for 40 or 50, its worth it more to just keep it in the dugout ICOE.
Now if someone is a penniless high school kid with 2 chickens a week as an allowance, any of them are worth the money, just so you can record something, and get your ears wet! Saying that blowing the 30 bux on it will keep you from getting the DW Fearn you want, probably doesn't apply here.
