My first was the 029. It was so impressive that it has led to 10 or so more PAM purchases in just the last two months. I just got the 390, 243 and 127. Love all of them. All uniquely different.
Also have 177, 036 and 005. Love all of those too.
I would go with 029 for first. Simple and clean and very well made.
But I'm a noob so I would rely on the opinions of others before mine!
