This Luhr Jensen rod is not that similar to a Sage 3113LB or MB. They are similar in length but that is about it. The Sage 3113LB (8-17 line rating, medium power) and MB (10-20 line rating, med-heavy power) are both a fair bit beefier than the LJ 11 footer with 4-10 line rating. LJ rates this rod as medium power 4-10 for me = medium light. This translates to not a great rod for chum and/or springs. Might be ok for coho and steel head depending on the type of water you are fishing.
If you are looking to get into center pinning my advice would to find some decent used stuff and try it out. No need to go high end unless you have lots of money to burn. Get a 10'6" or similar length pin rod in either medium or medium heavy power. Shimano Convergence, Fenwick HMX, Trophy, Okuma, and so on are great budget friendly options. These rods are mostly under 200 bucks new and about half that used. Same goes for the reel. I'd get a budget Okuma, Rapala or simialr budget reel. Sometimes you can find used combo deals for $150-200. Try it out and if you like it you can always upgrade later and sell the cheap set up or keep it as a backup/loaner.
Lastly, if you are going to buy new don't buy online IMO. Go to your local tackle shop and buy there. You won't save a lot buying new online and you'll have a much better buying experience locally.
Found this add on Craigslist. I'd buy something like this. As long as the reel does not have any major issue (bearings are shot, dents, wobbles) it would be fine to try it out. And if the rod is decent I'd buy that too.
