Tbh i got myself 2 1210's on ebay for like £400 posted. You can get a nice little 2 chan mixer for sub £100 quid. And just get a cheap dvs like iscratch mixlive for £40.
Then you can buy vinyl as and when you can afford it whilst playing digital with the dvs in the meantime.
Its a lot easier to add to an already decent setup than upgrade from sub standard gear. (not saying that gear you mentioned was sub standard, but you know what i mean).
I've always been under the impression TTX1's & 1210s are fairly on par with each other. At least that's what I've gathered from all the reviews & comparisions i've been reading.
