Casio G-Shock G-9000-1V Mudman

Today's watch is exactly like my G-9000-3V Mudman except this one is black with red buttons and has a non-reversed display. I guess the colors were inspired by the DW-5500, or "G-Shock II" which was reissued a couple years back. I haven't added any new mudmen to my collection yet, but I fear it's only a matter of time. Surprisingly, prices of these fairly common models have gone up in the last 6-12 months even from authorized dealers. I guess Casio isn't replenishing supplies of some of the older colors (like this one) and so when they're gone, they're gone. There are a few other colors I'd like to have and I fear if I don't jump soon, I'll end up paying "collector prices".
