I have a DiamondBack Edgewood ( ' got it as Xmas gift last year) with a suspension fork. I'm wanting to convert it to a rigid one since I mostly ride on the road and really don't see a need for a suspension fork.
What and where do I get it (best place to buy)? What dimensions/measurements do I look for?
Thanks in advance!

Check Bikeman.com and go to their components/fork section. They have rigid forks ranging from several hundreds to less than $50. NYCbikes has some too.

I concur, Bikeman.com is reliable and they always have good prices. The Kona suspension corrected fork would do you well. I got a Salsa for my 29er from them....it rides well but costs twice as much as the Kona.

My Kona Kula Deluxe came used with a Kelly Rigid fork and Velocity 29 er front wheel laced to a Shimano 525 hub. The fork is disc brake only. If you are interested in used, the Kelly is a high quality item. Both are Mint.

Thanks for all the help! I really appreciate it.
If there's more suggestions, please keep it coming. I have 'til the end of January to beable to afford one.

BTW...HAPPY NEW YEAR TO ALL!

Got to give a mention to the Project II fork. This was fitted to Kona's and is one damn good fork.

Please explain "suspension corrected" vs. "non-suspension corrected". I saw these terms as I browse at Bikeman.com
I assume it got something to do with the suspension travel or lenght. If I get the non-corrected one, will it lower the stand over height of my bike?
Please bear with me. I'm a novice.

A "suspension corrected" rigid fork is one designed to keep the front of your bike at the height it would be at with a suspension fork (the exact height is a little hard to determine, that would depend upon whether you used a 80mm travel fork, or a 100mm fork, etc.).

A "non-suspension corrected" fork will typically be shorter in length, and will lower the front of your bike. The overall standover height might be lowered a little also, but basically your frame will be "low in front", which could affect handling.

You probably want a "suspension corrected" fork.

Thank you so much.
I do want the stand over height to be lowered. I have a 19 inch frame and its a bit large for me. So, a non-corrected one will be the one I'll get.
According to DB website I got an Odessa 63mm suspension fork.

Last questions, promise!
How do I know if my susp. fork is threaded or threadless w/o removing it?
DiamondBack describes my bike as "hybrid", so, do I get the one for MTB or for hybrid (' planning on lightening the bike too, if possible)?
Thanks!
