First of, welcome to the wonderful world of pipe smoking :clap:
+3 on the cob... or a cheap decent briar pipe if you don't like the looks of a cob. Spend $50 and you're set for your first 6 months or a year. Here's some links to some of our site sponsors to make it easy for ya.
These are decent. Not great, but ok for a starter pipe:

http://pipesandcigars.com/romapipes.html (a bit better than the Leonessa imho)
http://pipesandcigars.com/brighampipes.html (ditto)
Smokingpipes.com has a "pipe Locator" button on the right. You can search for pipes under $100. Heck, for $56 you can get a Peterson Kapet and they smoke great. I have one with me right now. Here's a good example:
Nice bent one: http://www.smokingpipes.com/pipes/new/peterson/moreinfo.cfm?Product_ID=90979
Or a straight one: http://www.smokingpipes.com/pipes/new/peterson/moreinfo.cfm?Product_ID=91004
Finally, CupOjoes has a whole list of under $50 pipes. Look for the Roma pipes or even better, the Savinelli Florence are on sale for $49.

Then chunk the liner thing.. it'll keep souring up on you and destroy your interest and pleasure in pipes.
Good luck my friend, always feel free to ask.
