I've got the Delta 18/36 and it works well and I've got no reason to suspect the performax doesn't also perform well.
However, what you may want to do is seriously consider your requirements. They are a great tool if you do a lot of panels but they do produce a tremendous amount of dust and do require some setting up. I do do a lot of panels and find it a useful tool but it isn't the kind of tool I brush the dust off of for every little job or individual board that needs milling. There is a good chance that, unless you do do a lot of wide panels and after the novelty wears off you'll be reaching for you random orbit sander more then the wide belt sander.
A good dust collection system is a must. The job can be done with shop vac set up if you have one of those clean stream gortex filters and don't mind stopping every ten minutes or so to shake it out. All in all though, a regular bag system would best. Even at that the bags will have to be, at the least, shaken out after every use to maintain any decent level of efficiency.
Then again, a new tool is a new tool. and if there isn't something of comparable price that you really need, it is a nifty shop toy.
Good luck.
