I bought the 1st bass you mention, l/h and deco and only cost about £20. I still haven't found why it was a deco except that the pickup screws hadn't been screwed down properly. The bass itself is HEAVY and the neck, for me, is very baseball bat, modern C shape apparently. I tried it live and it didn't seem to project very well so I've put it back in its case and haven't touched it again since. I really ought to get it out again and have a fiddle and see if I can't improve things. All that aside and it well be just me, it is incredible value for money, especially if you can get a deco one. I've also got an l/h HB shorty and a Beat bass that I've converted to left handed. both deco and both incredible value for money!
Here's the page for deco if you're interested. https://www.thomann.de/gb/decorative_guitars_and_basses.html?pg=2&ls=25 you need to keep checking it though and maybe set up an alert as they sell very quickly.
