Light Pollution Filters

I have been doing a bit of reading on Light Pollution Filters and cannot decide if I should get one or not. Most of what I read is really a bunch of mixed reviews. Now my House is surrounded by a moderate amount of light pollution. Although I can take a 15 minute drive and get into some nice dark skies with little light pollution, I know I will do a bit viewing from my own back yard, hence my question. Is it worth it to look into these light filters? It seems that the debate falls with these 3 filters: Orion Ultrablock, Lumicon UHC, and Lumicon OIII. Has anyone tried any of these Filters, and Do they work? If there are other LP filters I have over looked that work, please post them here. Any advice is very much appreciated. Thanks.

Orion UltraBlock is "on sale" until at least March 7 (heard from one source). 2" about 1/3 what it used to cost, 1.25" about 1/2. I bought one of each 5 weeks ago on sale but still at much higher prices, oh well (yes I have put them to good use). At 16X the background sky would have been too bright where I am, so I use the 2" UB with a 32mm eyepiece and see more stars than without the UB. The 1.25" I use on M42.

One question is whether Orion is about to release a new version. Since they have a 30-day return policy you really can't go wrong...

$60 for the 2" and $55 for the 1.25", I believe.
