Can't say much about mills but I do know alder makes poor building lumber. Cut up some fir instead, alder will be nothing but trouble.
I built my band saw mill last year. 20' track w/ a 18hp and trailer tires. I can stuff a 3' diameter x 18' log in it. It gets to be a lot of work to push through the log so I'm planning on automating it with a gate opener. I shopped the prices on everything and ended up getting most stuff offline and it ran me $1400 to build it. x2 on the equipment, moving those logs is no joke.
Ah a sawmill thread...I have owned a chainsaw mill and now I own the harbor freight band saw mill. The band saw outcuts the chainsaw mill 10-1. So far the harbor freight mill has exceeded my expectations. There is a big learning curve but once all the kinks are worked out this mill will cut superb lumber. Looking at comparable mills I think the HF mill is the best bang for the buck. The biggest weakness IMO is the two piece track and getting that perfect for straight lumber. I also built an extension so I can mill up to 15' but I'm now in the process for building a new one piece track out of 21' 4"x3" steel angle. Wish I would have just done this from the start instead of building and third piece extension.I think the woodland mills have a very similar model to the HF and are probably built by the same manufacturer but cost more. Below is a link to a thread dedicated to the HF mill and there is a ton of good advice. The people posting on this site have done some really neat things with their HF mills and this thread was what finalized my decision to buy the mill. There was a coupon offered that brought the mill down to $1,799 and it came to just over $2,000 with shipping and tax for me.http://www.woodworkingtalk.com/f26/harbor-freight-tools-band-mill-7801/One other item is to get good blades for the mill. Cooks makes blades just for the HF mill and they are really reasonable at around $15 a blade.http://store.cookssaw.com/A piece of equipment is a must when moving logs around for milling.
