The price difference you are talking about sounds like cheap Chinese imports vs custom instruments from small shops. I would not recommend either source.
You can get a MUCH better instrument than the cheap junk by searching for 1970's/80's OMI Dobros and anything older. Most of the OMI's from that period are pretty decent. I have a '79 all-mahoganysquareneck with fancy inlay, and if I were to find a replacement it'd probably be priced in the $1000-1500 range. Plain ones like D60 squarenecks are usually $700-1000.
You can even find prewar Dobros - both squareneck and roundneck model 27's and some 37's - for under $1000, maybe $1500 at most for a very nice one (anything priced higher is either an odd collector's model or a seller simply asking for too mcuu money).
Vintage roundnecks work just fine set up as squarenecks - I just picked up a 1930's model 27 roundneck in excellent condition for $800 on eBay. It's set up with an extension nut and plays/sounds great. I've seen much of the same kind of pricing on eBay's European sites.
IMO you would likely find a much better instrument for a good price looking at older used Dobros. Just avoid anything after around 1993 (and do not buy anything with the name "Hound Dog!) - Gibson bought Dobro the following year and started cheapening things very quickly.
Just as an example, this is the 30's Dobro Model 27 I just bought. It needed nothing but a new nut, new strings and a bit of cleaning:
