Sorry I didn't get back sooner. Sure, either collimator will be fine if your planning to go with the reflector. You can eyeball it at first by just putting the scope way out of focus. You'll see a donut shape. That's the reflection of the secondary mirror on the primary. The center (hole) of the donut should be right in the center. If you want to try that before investing in a collimator, that works pretty good. But you do need an eyepiece for that. You don't need a finder scope to see if the scope works. It will be very difficult to find anything specific with out one. But I'm sure you'll be able to find the Moon and Mars. Maybe you should get a cheep eyepiece from Orion just to check out the scope. The Explorer eyepieces run $27.95. That's about as cheep as they get. It will be good enough to test the scope. Although almost anything you might buy will get used if you invest in a new scope so it's up to you. A refractor, does not need colimation if you decide to go with a new scope. Good Luck, Get an eyepiece first. Find out if the scope works. If the mirrors are intact, primary and secondary, it should.
That's it;
