Well... This thread has certainly devolved. I've gotten several good answers to my question though.
In response to a few posts, I have definitely made up my mind that I am going to purchase a sled rather than build one, regardless of how elaborate or how simple you may have made one.
I also do appreciate alternate suggestions but so far, except for the "Aigner", I have already looked at each of them before narrowing my choices to either the Woodpeckers or the Infinity.
Mark & Cyrus... I do have to admit, that when I first saw Mark's post that I thought $30 was way underestimated. However, it then occurred to me that you must have an enviable scrap pile (by the way, could you please give me your address so that I can come raid it...) so I for one didn't consider it a "lie".
Now, that I have caught up with the conversation, I would still appreciate any further votes &/or comments.
Thanks,
