Tape trading was the and your experience was basically the same as mine. I was first exposed to ECW thru the cheap wrestling mags first and ECW ran their tape ads in those mags as well. My first tape was when Bam Bam beat Shane Douglas for the world le, I think it was the night the line was crossed or some like that.
Bought tapes from a few of the "mainstream" traders in the early days of the net and then found "The Tapeman" Corey on one of the first boards I visited back then and this dude sold not by the tape, but by the hours so you got 3 6 hour tapes for dirt cheap. Essentially, it was make your own mixtapes of you couldn't get anywhere else for $20. That's how I discovered how bad ass the AJPW from the late 80s thru the 90s was. I know everyone has a hard on for NJPW these days but 90s AJPW was still the best wrestling ever. Kawada bombs, head drops and stiffing the out of the out of the out of eachother.
