I have the C shaped thing that I used to pull mine off with - as you say it was cheap on eBay - I would lend you it but postage will be as much as I paid for it
You need a tool to remove the steering wheel? Mine came off reasonably easily once I worked out how to remove the horn button to get at the big nut
Here's how I removed mine - the large C washer under it with a 2 leg puller - can't remember if I used 2 C washers or one
