Recommendation for a USB boot tool-kit

[lyor]

I'm looking for software that can create an ISO file for me that I'll boot via USB as a testing tool\installation of operating systems and so on.
I would like to have the option to include the ISO what image files I want in the same style (for example: MemTest86 or HDD Regenerator) as long as there is enough space on my usb-drive of course.
I'm aware that it is possible to do it with tools like Hiren's, but I would prefer something simpler as DLC-boot style, with a GUI.
The problem of the DLC tool, that it is pretty bound/locked up only for what their website has to offer, and can't operate with any other ISO's.
I'd prefer a open source program, but I won't really nag about it if there is none.

Hey there im not sure if this is what you are after

 

but http://www.easy2boot.com/ lets you boot from multiple iso/images from one usb. Comes in handy to have all your tech software and windows versions on one usb
