Query: Missing commas as separators

I have the TI 30X-IIS, a nice dual power, 2 line calculator. It has one feature missing, the fraction bar key, that another TI has. Other than that, pretty much the perfect machine for me... except it does not use a comma in numbers to separate the thousands place: it displays ten-thousand as 10000 instead of my preference 10,000I know, most people probably do not care, I must have some kind of dyslexia because when I see 4589339 I have no idea what that is, as compared to 4,589,339 which I instantly recognized as 4 million, 5 hundred thousand,etc.I'm looking around for another calc, one that has a 2 line display, that works with fractions and decimal conversions, the basic stuff, AND displays numbers with the lil' comma. I would prefer a TI.
