Freddie,
No worries. They do a great job re light "quality" and features for a nice price. Also, bear in mind, it's not like these things are dropping to the floor like dead flies everywhere - but the compromises made in the physical construction of the units (new or old) should be in the back of the mind of any DLite user. I'm sure folks stretch them with larger mods everyday - but sooner or later.... I've since moved on to Profoto, but I did manage to fix my broken DLite (PL Premium adhesive - epoxy just wasn't strong enough). It was MUCH stronger then new, but man did it look like hell.
I'd just wish they'd re-done the mounting system with the IT versions instead of just carrying over the dovetail. Adding a 'thicker' plastic shell and BXRi swivel is all well and good, but it's still two 2" strips of 1/8" plastic keeping the light attached to the swivel. Knowing in detail now how the DLite swivel-case interface works, I'd NEVER a DLite (again new or old) in a boom situation without a safety cable attached to the light housing itself -- NOT the swivel mechanism.
One thing in most folks favor is that Eli OEM boxes (and cheap Ebay units) use thinner fabric than units from say Profoto, Aurora, Chimera, etc., so the heaviest part of the boxes tends to be the speedring - making them not only light but the weight more rearward biased - easing stress on the light.
If you like the DLite features, the next step up, the BXRis, share all the nice points of the DLites (save the price) and then some -- and are MUCH better constructed from the aspect of using with whatever modifier suits you.
The only caveat with the BXRis is that the swivel handle (shared with the new IT DLites) is not the greatest. It can strip if you over-torque it. That said, the handle from a Manfrotto 026 is a direct substitute and locks the swivel like a pair of Vice Grips. Again, more DIY you shouldn't have to do, but very effective DIY.
Good luck.
