Meerschaum Market is a great website for a meerschaum pipe. They have a lot of pipes on clearance, pipes under $100, and many pipes at a great price point. They have multiple master carvers listed on their site as well.
Altinay and SMS make a great product as well, so you would do fine with one of those as well.
If you are looking for the best quality meerschaum with a briar style tenon then I would recommend IMP, but you'll be paying $200 and up for the pipe though. Definitely a quality pipe.
I also have two Strambach pipes, and out of my 20 meerschaum pipes (most Turkish) one of my Strambach's is my go to pipe. I smoke it more than any other meerschaum pipe. It smokes like a true block meerschaum pipe; however, it colors a bit slower than genuine meerschaum. I have a couple African meerschaum pipes and they smoke very well, but again they won't color like the Turkish meerschaum, so if coloring the pipe is your attraction to the pipe then I would definitely recommend Turkish block meerschaum.
Good luck finding a new pipe.
