Ok, I finally got my SlingCatcher.
Ordered it from Amazon but had to have it shipped through freight forwarder in Miami since Amazon does not ship this device directly to Colombia.
I paid around US $ 164 for the SlingCatcher, plus a few $ more for 2nd day shipping. If ordering from Amazon, this is the best price you can probably get. I monitored for some time the price and this is the lowest it has been. Most of the time price has been near or above $200.

Installation was really easy, no problem at all, connected immediately to my Slingbox from SlingboxNYC. So far everything has worked perfectly, streaming speed has been above 1000Kbps most of the time, sometimes higher, sometimes lower, but good quality always. 

Only issue is that it seems that the guide that SLingPlayer has, the one with the nice UI and channel logos seems not to be present with SlingCatcher, and it seems it only has the normal DTV guide, so I miss that guide. Also,  I am not sure if Close Caption option is available with SlingCatcher...I have not seen it.

So, in summary, SlingCatcher is working great for me, SlingboxNYC is probably the best provider (best offer, best price, best aftersales service, etc) you can find for hosting your SlingBox, and if you really want to see your SlingBox in your TV instead of your PC, I think it is well worth it to buy the SLingCatcher.
