Now there's a tough question. While I have always been a firm believer in "you get what you pay for"' these days with hundreds of attachment manufactures it is tough to know who's best (if there is such a thing) and best for who, as everyone has slightly different needs, and who is just trying to make alot of $$$
I try to honestly ask myself, How much will I use this piece? How hard do I need to be on it to get my job done? Of course the price is a concern for most of us in there some where as well. If I use it alot, I can justify letting someone make a few more dollars off me.
One thing about being a member of a forum, you have access to alot more feedback.
I can't say that I have every had a truly bad attachment. But I can say I have alway got what I paid for. If it was cheaper, when it arrived I could see where they saved a few bucks.
I bought some pallet forks out of North Carolina a few years back. They were 500.00 each. They incuded in free freight to Mn on 5 units. The Brick gard was 1/4" material where my Bobcat forks are less then 1/8" The tines where made in Germany, and to my knowledge no one has broke one yet. (I sold 4 of them) But on the downside. The holes in the brickgard where torch cut and not ground smooth, (wear gloves) the top hook for the fork to slide on was 1/2" (I had one noname set that was only 3/8) where as the better sets are 3/4 and machine on a angle to match the hook on the tines. The sharp edge on these made the tines hard to slide back and forth. Finally the paint job was poor quality. Did I get what I paid for, absolutely. They were 150 to 200 less then some of the bigger companys, and I give them credit for cutting corners on things I could live with. They are tough forks, but I do curse them a bit when I have to get the 6lb hammer out to slide the forks.
Price wise there are the big OEM's like Cat, Case, Bobcat etc you will get a good attachment, but your paying to have that name on there too.
Next in line would be the attachment only companys Like Bradco, Erskine/Quick Attach, Loflin, Sheyenne, Ati,... who make a OEM quality attachment, sometime better in their specialty area, but the price should be a bit better.
And there are hundreds more small shops that do custom build individual pieces and small production runs of the most common attachments. Some are excellent, some are light duty only, This is a real good time to ask about quality of steel, thickness of critical parts. Look for grease zerks (or the absence of) , bolts instead of pins, tie rod hydraulic cylinders instead of threaded barrels, hose wraps, protection and routing.
Now don't get me wrong, there are some of these shops that are very good, but as a whole their market is the customer with the least amount of money to spend. So there will be some corners they have to cut.
Hope I have'nt offended too many..
