Hi, I am relatively new here, but I have been reading Spidey comics for about 15 years. I mostly hunt down back issues, because I don't like direction of titles like "Amazing" because of JMS-his Totem arc and the Sins Past issues really bothered me, thank goodness he is leaving the series so I can start reading the core title again.
Anyway, if anyone is interested in older issues, there is a place in Denver called Mile High Comics that has great deals on anything in Spidey's past. For example, I ordered ASM 31 (first appearance of Harry Osborn and Gwen Stacey) for under $100, and ASM 40 (Norman Osborn revealed to be Green Goblin) for a little over $100. Both these comics were in really fine/near mint-mint condition. I have done business with these guys in the past, and shipping usually doesn't cost that much at all. I recommend them to anyone who is interested.
