Thank you all very much for your answers. I think I have really explained myself badly maybe. I might be able to make regular online purchases through a family member, maybe my father who lives in Florida. Recently they reapproved the import led for parts and model airplanes that was denied until last year. There is still some paperwork to be completed, but everything seems to be going smoothly. This means that soon I will be able to import parts and parts legally into the country.
I am going to explain a little about how imports and online purchases work here:
1- First I need to search through internet for the best prices sacrificing quality many times.
2- Hubicar the product and then ask a family member to buy it for us.
3- Wait until some person or mule (person who is dedicated to travel to the country with merchandise from failiares to deliver charging per lb.... the price ranges between 30 and 40 usd each lb).
4- Another variant that does not always work is to send parcels by mail, but I have the bitter experience of having received shipments from several of you and having them rejected by customs here in Cuba. Besides this takes up to 4 months to reach me and if the package exceeds 1.5kg I have to pay a very high tax for each extra kg.
As you can see, I'm really fu*****ed. This whole process can take several months to obtain results. That's why every purchase i make should be as safe as possible, and guarantee that what i buy will last and that iwon't forget anything.
Buying a radio like the Jumper that is compatible with different protocols is fine, but I don't know if it's what I'm looking for.
This is the radio i am using now

The only thing is that i need somethig better to move forward. And considering that I could make a purchase every 6 months or so, I need to find something that is reliable and has good performance.
The ideal would be 1 Tx and 2 or 3 Rx but I will be happy with 1 Tx and 1 Rx all under 160 usd. I understand that you can't buy good things with little money. I just want to find the least bad for that price.
