I have a set of Blackburns with curved hickory handles, 5/8 fixed nose die and die cavity for my O, D and 840 diesets. Those are the dies I use the most. A friend has a complete set I borrow from if I need something odd. The tool is not too expensive @ around $300.00 but the diesets are better than $50.00 a set. It can get real pricey if you need all of them. A dieless hydraulic would probably be more cost effective. The Greenlee Gator is awesome. One-handed crimping or crimping in a narrow ditch is a breeze. Too expensive for me no more than I need to crimp H-Taps.
