Xeon,
They were exactly my thoughts too, but I got seduced by that siren aka NX GEN.
Plus I had to pay another $20 shipping!

After I finally found ORWG and that it worked for me, I vowed not to waste any more time or money on trying other glues.
But after about 5-6 years loyal service, I began feeling ORWG was letting me down.
Also, the price of it here in the UK kept going up.(currently £12-£13 a bottle)
When I look at the size of a bottle of ORWG compared to the size of NX GEN, there probably isn't that much in it price wise.

If it works for me, I hopefully won't resent the cost as much.
