need advice, the dumb questions continue. Options

so by now i think most of u guys probably know my problem.
(my engine needs to be replaced)

1. i was just wondering, would it be better/cheaper for me to get a used engine for ~500-600 and then pay someone to install it?
2. just pay someone to take mine out, rebuild the engine again on my own, and then pay someone to install it back it?
3. or just get another used celica/camry which is working for about ~1500, and then pay someone to swap the motors?

the labor of swaping/taking the motor out and installing another one would be ~500

if i choose option 3, i have the advantage of parting it out, but disadvantage of paying tax tittle, and registration fees.

i just cant make up my mind,
alot of u guys have experience, and i just need some advice or suggestions.

ps: i saw this car on craiglist, could u guys also suggest what the problem could be (tranny or computer related) and if its worth 1800?http://houston.craigslist.org/cto/2386508388.html

thank you and sorry for another dumb question
