Hi Matt. There is a 4.5" Meade Cat on Gumtree (in Bridgewater) for $200. Has some eyepieces and a diagonal. It's not mine, & I don't know the seller or it's actual condition. It looks to be an older scope but maybe worth a look. It's on a manual EQ mount.
Here's the link.

There are a few others on there including a couple of 130mm Newtonions (none of them mine either BTW).
Cheers & happy scope hunting.
