ThisThis is fairly normal. My anecdotal advice would be to try to tamp it down as much as you can or you will end up like me. I'm 3 years in and have already sold off probably 70 pipes from my collection, most of which I bought in haste in the first 6 months.
I found later on that once I realized what I liked in pipes (after buying countless savs and petes) I would rather spend more money less often on higher quality pipes.
