I always recommend the eclipse brushes, though usually the hp-cs. The only difference though is the cup, the cs is bigger and has a lid. Its very reliable, and as mentioned parts aren't the cheapest (and not the most expensive either) however they are very tough and hard wearing, so with correct handling they last a long time, so IMO it balances out.
Its a great brush to learn on but you wont outgrow it, it is a workhorse and very versatile, and although not a detail brush, the more you use it the more you get out of it, including very fine detail.
If possible I would ask to see the brush(es) in action. Make sure there is no paint getting into the back of the brush, no bubbles appear in the cup when in use. That it sprays clean. Check the needle and nozzle are good, no cracks ir chips and that the needle is straight an whole at the tip. If so then parts will need replacing, depending on what is needed, when you add it to the $80 it might work out better to buy new.
I don't know much about the Krome, with a .2 (I believe
) nozzle, its more towards the detail side. People on the forum love them, but I do notice a few more issues popping up, although that could be user error. And Badger do seem to have great after sales care to resolve issues.
