Although Strad never made a bass, marketing geniuses for a century or more have been using his name to give an air of quality to entry level instruments. Value-added is a term that applies, but that doesn't mean this may not be a good bass for you.

It looks like a Chinese or possibly German laminated bass in pretty good condition. Problem areas would be:
1) Broken or re-set neck. Look for evidence of repairs at the heel area at the top of the back.
2) Dyed maple or otherwise cheap fingerboard. It looks like ebony, but the pics don't show much.
If you can post pics of these two areas that would help.
Assuming these are good, I would feel comfortable offering a between $750 and $1000.
What are they asking for it?
P.s. the bass would benefit from having the stiff tailpiece wire replaced with flexible cable and probably a set of strings. Also, sight down the fingerboard from nut to bridge. If there are any high or low spots it should be dressed. These things cost money, so figure that in.
