Get an el-cheapo MFT to EF adapter. I just picked up a 'fotasy' of this type from amazon for about $20.
On a limited budget you're not going to get a 'smart' adapter, so you won't be able to manipulate the iris or enable optical image stabilization. But the lenses will otherwise work just fine. To figure the relative focal length they'll behave as, multiply by 3. So if you have a 35mm, it'll behave like a 105mm on the pocket cam, more or less.
Then eventually down the road get yourself a metabones speed booster, and the sensor will behave like a super 35mm sensor..
you CAN adjust the aperture of those canon lenses.. you just have to do so on a camera that has a smart mount, then pull the lens off with the aperture set as desired.
The cheap adapters with built in manual aperture are not ideal because the aperture is in the wrong place for the optics, so you'll get vignetting the more you stop it down, kind of defeats the purpose.
I've not used it, but since it allows you to use the lens' aperture it'll be much nicer than the after market manual aperture adapters, since the aperture blades are in the proper place within the lens elements.
Just watched a video the other day of something similar, but it was a DIY live-lens adapter.. pretty cool.
Assuming the one you picked up from ebay is in good shape, you'll likely be very happy with it. If I were you, I'd probably keep it in my camera bag even after getting the metabones adapter, since it'll effectively double your lens collection...
