Yashica Mat-124

My craze for black and white photography, especially B&W portraiture, has been rekindled lately. I began reading up on B&W photography from various books and forums. What I've gathered is that medium format cameras give superb results on B&W photos.
I have a TLR camera (Yashica Mat-124) which was given to me by my dad. However, the shutter is not working. From one particular forum, I learnt that I can send my Yashica in to "Mr Tay" (http://www.decameraconsultant.com/) for repair. Will check it out and get a quote for the repair. In the mean time, I'm looking for Seagull WWSC-120 which is within my budget. (http://shop.lomography.com/seagull/)
