Since there are hardly anyone experienced with the Kata "EPH" bag system on this board, I decided to just go ahead and order the two items aforementioned. From all the information I could gather from other sites (one -- and only -- 5 star review at Amazon.com for R-103), I think I've made the right decision in going with the "EPH" (Ergonomic Photo System) bags that are modular for greater versatility. I ordered them from the Midwest Bags (midwestbags.com). While the prices are the same as B&H and others ($62.95 for T-212 and $159.95 for R-103), the Midwest Bags are offering free shipping plus 2 gift bags to choose from (Baby Scarer, Ripsnorter, or Lollybag cell phone pouches with the order of more than $150). That puts them about $50 cheaper than their competitors. The service is also excellent with lightening speed of response. I don't think I've ever had a service faster than these folks. Absolutely no waiting when I called. My order was out in less than 20 minutes, believe it or not, to FedEx. They made you feel like you're the ONLY customer. WOW!! It was so good that I'm wondering whether these people are real (or whether I'm gonna get my stuff for real, lol).
In any case, since there are lots of questions regarding bags and brands and so on on this forum, I'll post my review upon receiving and using them.
