http://www.satelliteav.com for the microHD, 36'' dish and other items etc.
The owner of this site answers questions here on a regular basis.
I just ordered the 36 ''geosat pro dish with him, he stands behind his products and if you have questions or problems he will help you.
He also sells on amazon and e-bay.
There is also a thread here on site about the microHD receiver you may want to read.
''Would I be better off just using the 7.5' for c band only, and getting a smaller 36" dish later on for the ku?''
I started out with an 7 1/2 foot c-band dish about 1 year ago.
I got a BSC 621 D2 LNBF for it, which can do C and KU on the c-band dish. Overall it is good but not great. The problem is, if you peak this LNBF out on c-band then your ku band will suffer ...or vise-versa...You have to find a median for it , but you may suffer on both bands.
When my 36''dish comes I will peak my C/KU LNBF for c-band only.
Most likley I will use the 36'' dish with an motor in addition of the c-band. All can be used with just 1 receiver.
Some members here have 10 dishes or more.
A KU or C dish/ dishes can be added via a diseq switch/switches at any time using the same receiver.
Be careful of cheap receivers that may be outdated or do not get supported anymore, like my S10 receiver.
Some outdated receivers may not be able to receive HD signal or S2 signals, which more channels are going to this format. That's why I and other members recommending the microHD.
Some receivers are clones and when you try to update them it may kill them.
Some receivers are sold and shipped from china and they give you 1 year warranty, which you actually have no warranty at all since chinese customs will not allow you to ship a receiver back into their country and they will distroy a receiver if it is shipped into china.
That's why you want to buy items from a reputable seller.
Thats why I said before,.... before you buy anything see what we think about it. That may save you money and frustration.
What would I buy today if I would start with this FTA thing like you are planing to do ?
I still would get the C/ KU LNBF, this way you can get C as well KU bands and you can see what c and ku has to offer, since you should be able to get strong transponder in KU .
I still would get the V-Box 7 to move the c-band dish.
And I would get the microHD from satelliteAV, since he provides full support for it and because he is located here in the US and members here have good things to say about this receiver.
Later on if you want to add a KU dish all you need is a KU dish, a LNBF, a motor if you want to go from sattelite to satellite and diseq swith.
E-bay would be another source, but it is hard for an beginner to see and to know what they are looking for without getting ripped off.
