The VApex screens are not terribly well built, but work well enough. It is a very 'entry level' screen and long term reliability and quality really is not known. Since you were told it is 'crap', you should likely get an explanation from that person as to WHY it is crap.
The Espon 5010 is also a fairly bright projector. If you primary focus will be on 2D viewing instead of 3D, then it can pretty easily handle a size of 133" with a 1.0-1.4 gain structure on the screen.
If the VApex screen is anything like the HTDepot screens, then they have a so-so screen frame quality, the material is a bit thinner than a mid-grade screen, and it uses a bar type tensioning system which can leave a couple of wrinkles if not proerly installed. The frame is not as well built as other screens, and the surround fabric is not very thick and may be a bit loose on the frame. BUT: If carefully assembled, a properly hung, and gently handled, it will last for years without issue and will provide a very good image for years. It will be a nearly unnoticable difference to step up to a entry level DaLite or Draper screen, but their build quality would definitely be better. Image quality? Not much if any noticable difference.
