which is a better buy?

alrite so im still not sure if its my tranny, but i will be pulling it today or in the next few days. So i have 2 options here if it is my tranny. option 1- buy a eg ex tranny from a local importer that has 40,000 miles on it for $350, which mind you this is the place where i got my last tranny. Option 2-i found a ek cx tranny from a guy off craigslist and he says that it has 130,000 miles on it for $150. So the gear ratios are different, but not by much. Here is the gear ratios for both tranny's & tell me what yall think and what is a better buy:
so here are the gear ratios for the cx and ex:
cx:
1st-3.250
2nd-1.762
3rd-1.172
4th-0.909
5th-0.702
reverse-3.153
final drive-4.058(coupe/sedan), 3.722(hatch)
Ex:
1st-3.250
2nd-1.909
3rd-1.250
4th-0.909
5th-0.702
reverse-3.153
final drive-4.250
so here are the gear ratios for the cx and ex:

1st-3.250
2nd-1.762
3rd-1.172
4th-0.909
