I went the ETC (or whatever seatpost manufacturer company is called) route not long ago especially because they had long seatposts (many vintage ones which I would prefer were exceptionally short or shorter than I'd prefer) and because I was on a tighter budget at that point. I got a 30cm long seatpost and just cut away the excess with a standard hacksaw. It's definitely worth considering if you're looking for something inexpensive and solid. Of course, you will have to measure the minimum insertion point and make sure you use that length after you modify the seatpost. The advantage of these cheap makes is that they can have any diameter you might want.
