Yes, the market for the 250 is insane. A couple years ago you could buy them direct from Japan for $50-75. Now, they are about $189 retail in the US Market, sell out instantaneously, then end up on ebay for well over $300. A new version of the 250 (with supposedly amped up production) will be hitting the market in 2015, but like the new 175 version, the increased production won't make a difference and they will still sell out fast. I throw the 250 on a XH swimbait stick rated for 5-8oz, some guys use a heavier rod than that.
The Mother, is just huge, but there are larger. Also another hard one to find. Apparently Tackle Warehouse has a $20,000 backorder log on Roman Mades.
