Random cheapo Newtonian to try collimation?

[TiffsAndAstro]

Missed out on an Orion star blast 4.5 for £35 was wondering about the one below. Not bothered about the mount.

Just thinking about a cheap non bird Jones F5 ish Newtonian to try out collimation before maybe buying something better that won't needs lots of fixing to make it good, in the future.

This OTA weighs 4kg so not impossible for my current mount.
