My thoughts of all in one sets: sets are good, if you get a complete set. there is a possiblity out of thirty bits you'll use 30% of them, and you'll need 2x or 3x of what you get of those types of bits you do use. a big one. If there cheesy, you may be better off in the first place buying better specific sets. You don't need to buy big sets from big names. There are somes types you definetely need all sizes! You could think of your nexrt project. You think 30 is a lot, until you need it. 1/4, 1/2, and 3/4 for sure, say straight bits. You could start one small set at a time with a full set of all sizes: straight, oggee, roundover, beading set, rabett, & other great likea rail and stile panel set. You won't get a full set of any of those. Then what do you do? Count 'em. You will be lucky if you can get through your first project with an all in one set. And you won't be able to do some stuff all together. Changes abound. Look at the set and see what sizes of each of these you do get! 1/4, 3/8, 1/2, 5/8, 3/4" of anything, not! its a grab bag You might get grabbed! A panel set is an awesome thing to have. Expensive. Nothing like it in an all in one set. Nothing you can use. I have a good Ti 26 pce set, but DON'T have a lot. A total hit and miss. But there good, so I'm happy. I want to buy a set of undersized plywood bits, not one. all undersized by the same amount, and in
3 sizes. No such tyhing in a big set. No tight plywood dado joints. Think abou tthat, righ toff the bat; no tight joints, no panels, hit and miss profile of any kind or size, and tons of crap.
Alternative, get an all in one, and deal with it, and fill in if you need it in the future. But you'll have to buy sets in the future, so you'll duplicate everything you bought in the first place. Its the things you'll need once in a blue moon that you get lots of in an all in one set
