Good write up Ducky, as per usual.
I wanted to do a comparo between the MC, and the eliminator. Not sure about that Marmo fella, but over here we had both, but whoever was behind the Eliminator, at least over here wasn't up to the marketing of the item, pretty much a machinist doing a second job making router collets to spec. or so it seemed, by what was written.
Now today, there was a time when Eliminator just went away, near, or around Covid, maybe went out of biz? I kept seeing
Muscle Chuck, and had purchased one to make that dodgy POS Bosch router I bought based on reviews, at least usable. Before the chuck was so poor it was unusable in my experience. It is a wonderful piece of work, and I think well worth the cost, which most find a bit high. Since I rarely use that Bosch router I an able to use it on a router motor I use in the table, and it makes bit swaps even easier. I have not had any balance issues, but they have a part of the site where they deal with balance issues. He did back then, and still does have a 30 day, use the MC, and if not delighted, he'll refund at 100%. I do not believe I ever saw that on the eliminator, and don't "see" it on the Infinity info. I think thats a big deal, but I'll admit to being kinda weird.
Now
I see Infinity has at least either bought, or stolen the Eliminator name, and are starting production of a few routers. they are listed on the sales page at the link just above. I am heavily invested in several of their products, and for an American based company they offer very well made products
A comparison today would no doubt have the Muscle Chuck as winner, just because Derosa engineering has their poop all in one bag, and it's a large bag, with lots of product choices, and a darn good product. Infinity looks to be in early development, and just plain doesn't have enough routers they can be used on, plus that 30 day use it, and return if not delighted thing.
