The Yeti I picked up was going really cheap at the time. Think I paid £65 for it at the time, 2 weeks later, the price shot up to £115, so yeah, kind of got lucky like you.
The problem with gel or rubber pads is that it won't help much when typing or moving the mouse around on the desk. I tried the stacked mouse mat trick, you get 5 or 6 rubber mouse mats on top of each other and put the mic on top of that; some of the vibration from me typing was still getting through. It sounded like I was in the middle of an earthquake when typing due to the rumble, but the Yeti is really sensitive too.
A couple months ago, I picked up a boom arm. It came with an integrated mono XLR cable, but the springs are really stiff. The Yeti is not a light microphone, it's huge and heavy; the Samson PSO1 pop filter is also heavy. The two combined on the end of the mic stand... it didn't budge and is still really stiff. Was very surprised. I would link it, but it was unbranded and from the UK, so I have no idea what it was. The closest i can find in the US is this...
That comes with a shock mount too, mine did not. I wouldn't feel comfortable saying they are the same, but they are damn near close. Even down to the g-mount for the desk. Excuse the mess, but this is near enough my setup (though I have since moved things around).
