I make my own, you need an 11 dollar toroid, a short piece of #20 enameled wire, a 200pf 5000v capacitor, some sort of a case, a socket to connect your pl-259 coax plug into...that's about it....just cut to size and string it up and it will work a single band or multiple without need of a tuner. You can buy ready made but don't get the one from MFJ as it has bad reviews.
The image below is a low-power version...you can see how simple the thing is...just a bit of soldering involved... this is a 20 dollar kit from qrpguys.com the 100watt version is the same design but you use a larger toroid that cost 11.00
