One upside to 30-30 over 35rem is that it's available everywhere from walmart to the gas stations that stock ammo during hunting season, and with the new ballistic tip ammo available, it has all the take down power you need for white tail.
I'd wait until January or so and start looking for a lightly used drilled and tapped 336. Lots of people seem to sell them after hunting season's over and heating season's in full swing, so you can often find them for not a lot of money.
I have a fixed 4power on mine, and it works phenomenally both in the brush and out to 100 yds or so.
