HW EZrun 150a esc or refurb MMM?

[scarletboa]

i sent in my defective EZrun 150a esc to nitrorcx for replacement 5 weeks ago and got an email from them saying that it is out of stock and they will be out of stock for 4-6 more weeks. they have offered me a 2nd option. i can get a full refund from them instead of waiting for the esc. i have seen that CC has the refurbished MMM esc for only $100. the only problem i have with that is, they are the v1 and v2 monsters and the warranty is only 2 months. i know they have a high failure rate and i am afraid to chance it. i'm pretty sure the EZrun has a 1yr warranty just like the non-refurb mambas do.

so, what should i do? wait for my EZrun, or get a refurb MMM?

also, another thing to consider: i have the program card already for the EZrun. Do the refurb mambas come with castle link?
