Absolutely not true. But you can look at your $200 GPS, get the bearing to xyz, say 271, and then call ATC and ask for a radar vector direct xyz on, like 271 deg. (wink, wink). ATC knows what's going on but if they approve the vector you're good to go. But technically it's a vector, not GPS navigation.

Maybe I misspoke. I didn't mean you could ask for GPS routing instead of your approved VOR routing, but you can ask for direct to a fix or airport in a radar environment - without /G equipment - and it's OK with them, traffic permitting. I've done it and told them I had a Garmin 496. I've even been asked if I had the ability to go direct. When I said yes, they said 'cleared direct'.
I do not like the title MINIMAL Compliance with 91.205 for IFR.
As far as the FAA is concerned, you are in Compliance with 91.205 for IFR in your Experimental or you are OUT of Compliance and not LEGAL for IFR.
Operating Limitations require compliance with 91.205 for IFR in a Homebuilt Experimental. You comply to legally fly IFR or you are illegal flying IFR.
Now if the title said least expensive compliance with 91.205 for IFR this would be a much better title for this thread.

My opinion
In my opinion, there can never be a gps box legal for IFR approaches that is not TSO'd. It is not just about accuracy or reliabilty; there is more to it. I have accepted that I will need to spend for one if I wish to do GPS approaches.

I dunno about that... last year in my minimally equipped RV (1 VOR, G496) I flew IFR from a private grass strip N of Houston to New Orleans Lakefront; since I don't have IFR GPS capability I filed /U equipment and VOR airways. But, when I picked up my clearance on the ground via cellphone, I received "cleared direct KNEW". No questions about headings or vectors, just "cleared direct". I thought it rather odd, but went ahead and flew it anyway. I wonder if it's a case of ATC figures most IFR traffic these days has an IFR GPS? Maybe it's ATC being, ahem, "lazy", and just getting me on my way and out of their hair...

I think the largest market (at least, the largest part of the market for a specialized piece of equipment) is not homebuilts with advanced EFIS and other features, but certified aircraft with largely analog instrumentation. An all-in-one box giving you a moving map, approach capability, COM, NAV, and ADS-B display is really valuable to that market, and a great bang for the buck.
A bare-minimum only what you need to fly a GPS approach box isn't going to sell as well. We want one for our airplanes because we generally have the rest of that stuff already.
