      Rick,

      You don't need a reflow station.
      Watch the videos of people using a $15- embossing gun from Hobby Lobby.
      It works fine. I warm the whole PCB up on an iron skillet/Hot plate (on low) first and then hit it with the air from the embossing gun to flow the solder paste.

      Assembling the Ensemble RXTX is my first attempt at an SMD kit. I know, I should have started with something easier. I've found I have to slow down and really take my time, and have the right tools. I don't feel I've yet discovered the best method for soldering SMDs. I probably need to purchase a reflow station as I've now returned to soldering the old way and it is most difficult even with a small tip.

      As for kits that might be pre-assembled, it is my understanding that this is what Genesis kits are doing. Most of the hardest work is done and I would think that some builders might appreciate having options when they purchase a kit. It seems that the industry is moving towards smaller and smaller technology and it would be a shame to  shut the door on Hams wishing to build their own equipment (remember like the old days) but be challenged by the problems presented in handling such small devices especially when hands begin to shake, eye sight starts to fail, etc. Kit options might be as follows:

      1. Complete kit with no assembly
      2. Kit with SMDs already soldered
      3. Kit with only the coils wound but not soldered
      4. All SMDs and coils mounted

      This might be too much to ask of any small time business tailored to the hobbyist, but I would see it as a real plus and I suspect some will pay more for work pre-assembled making their job a bit easier.

      My 2 cents
