Don't talk about it - just do it.
You can save money by going with a 2ch - 4ch is nice but rarely needed.
You can also save quite a bit by giving up some resolution... it does not have to be 400Mhz+ - even 100Mhz is great - or 20Mhz to start with.
Remember to budget for a probe that is rated for at least as fast as the scope - most people underestimate the importance of the probe. They can cost you $100+ if you buy them so start looking out now. Dont pass by the crusty looking one on the bottom of the drawer... there are some really nice *really old* probes around that kick the crap out of an ebay probe.
There are some things an engineer just has to have
If you want to be successful you have to have a scope.
Do it bro - I promise you will look back and wonder how you ever designed with out one.
Spice can never simulate the parasitic realities of your prototype. I dont even simulate anymore since all it ever does is disappoint me. Easier and faster to just build it an measure... and some times I find solutions by mistake in just doing it.
