I wouldn't use any of those scope for stalking if you already have one on a rifle that is ready to go. They will simply not be much (or at all) of an upgrade on what is atop the rifle at the moment.
I have a Diamondback HP on a little rimfire for bunnies. That is the supposedly better version than the one you mention. It is fine in decent light for rabbits and mechanically is sound but it aint no stalking scope. It is quite poor at last light IMO. I would never put it on a stalking rifle when you might need to shoot a deer on a dark background in failing light. It will let you down.
Don't take shortcuts with Optics. Use what you have until you have saved at least 400quid and then buy something like a 3-16x42 Baby STAC or find a SH Delta Titanium or similar scope with proper optical performance that will offer you a mag range that is useful and will provide you with all you need for a long time.
