As others have stated, you can't get along without clecos. The hand removal tool is $12-14 and you really can't get along without that.
On the other hand, if you want to have a tool that no one else on your block has, get yourself a pneumatic pistol grip cleco tool. Here is an example:
Avery Tools LP - PISTOL GRIP AIR CLECO INSTALLATION TOOL
I'd have to say that one could get along without one of these unless you did sheet metal for a living but the "gee whiz" factor is nearly 10.
