Just to voice my 2 cents. I also received friday my rti remote from etronixs.com and had very good service.
Now i have to wait for the new RS-232 sensor to come out! 4-cent's: don't know about the company above, sounds kinda fishy, why would you not want to make any money on something you are selling. I suggest you call RTI before ordering from them, get the low down.
