If you plan on using it a good amount without hearing protection, and you value your hearing - get a festool or a fein. It's a BIFL purchase. Other shop vacs will last a while too but the quality of the fit and finish isn't there. The plastic parts will break easier and leave you wondering whether to repair or replace and the answer will always be replace.
I have a stinger that stopped working. I paid 18 bucks for it, kind of a no brainer. Garbage bin.
Also, if you have an old home and therefore lead paint, a quality HEPA filter makes a lot of sense for any construction project that will be disturbing lead paint.
