Well, these aren't Gen 1 Transformers, but as close as you will get 25+ years later.  I love the detail of these guys, though I admit I hate the complications of transforming them.

First up are the Masterpiece Transformers, that as of this writing (Summer 2015) are still an ongoing production with Takara and Hasbro. I have really been focusing my Transformers collecting on this series the most the last couple of years. They come out several times a year, and are not really what you would classify as inexpensive.  I initially tried to stay true to my American roots and get the Hasbro ones.  That changed at about MP10 when I really felt Hasbro did a poor job of turning them around and getting them out to American consumers, both in speed and availability.  My stance has turned since then and now I get the Takara ones when they are released, and only hunt down the Hasbro ones if it is either ones I have missed, or Takara didn't release such as Acid Storm.

Alternators! I completed my collection and have all 27 Alternators released (have sealed ones of everyone, as well as many opened copies to go with them). Also representing these guys are an artist rendition (not box art) of each character. I am not sure of the artist though some seem to be signed. I forget now what website I found them on, but they are great. If someone want to write to take/give credit, let me know.

Finally, below the Alternators I listed Takaras Japanese Binaltech and Kiss Asterick that aren't represented in the Alternators line, as well as some good Chinese knock-offs/recreations.

 

Masterpiece / 20th Anniversary:



My Collection (with a few other things thrown in on the display) September 18, 2014 (Haven't got room for Soundblaster, Shockwave and Shackwave, so attached separate photo of them as I work to figure out how to gain more space for them all.).  As you can see in the images below, I started unboxing them in October 2014 after I got more Detolf cases to put them in.

MIA (Missing In Action! This section I admit is also an opinion section. I am listing key character I feel I really want that have not gotten an acceptable (if any) MP or 3P MP offering.
My main interest is pre-86 movie, so you aren't likely to see me list movie character and most after... In no particular order...)

Cliffjumper
Skids
Powerglide
Cosmos
Triple Changers
Combiners not Constructicons (Sure, there have been some nice 3P ones, but I don't feel they are quite MP level)
Headmasters (especially Scorponok)(except Weirdwolf who is done)
