I have a few favorites of my own, I think that what I like about them is not only the talent but how much they take time off to share their incredible techniques. In no particular order:
Mr. Cranky - Incredible when it comes to weathering and nice photos of his WIP
Mr. Lombardo - I love his creativity
Mr. Cruz - Love his paintjobs and cleanliness of work ( I own 2 of his creations)
Mr. Raitz - Lots of good stories and experiences
Mr. Geary - Love everything he does (even though I wish he would make a great comeback)
Mr. Downie - Also great with paint and cleanliness, very knowledgeable
Mr. Teresi - Plastic-surgery maniac
I have a few others but I have certainly learned a lot from these guys, I have PMed some of them with a lot of questions and they are always there with all the help I have always needed. Also, as previously stated, Gregg should be in this list, I can only imagine all the efforts put in to keep this boat afloat, never an easy task. Also, the moderators should have their minutes of glory!
