For what it's worth --I have liked mine--had no bubble trouble (lol) On my 100 I used two simultaniously because my tank is so dang long. Of the three I have two are still going and one did give out after 2 years. I don't know if that is considered good or bad as far as life span of equipment. Seemed like a little early to me.
As far as the biobale being a nitrate factory--well...
As I'm sure alot of you know.. my theory on this is --a piece of equipment ANY EQUIPMENT is only as good as the person who maintains it. Take good care of your stuff and it will take good care of your fish.
I got mine at <a href="http://www.**************.com," target="_blank">www.**************.com,</a> I don't know if they'll ship there though. Also you will want to seriously consider anthems advice on the better skimmer brands too. Buy the best you can afford when it comes to skimmers.
Good Luck
