EDIT: Just recognized you were asking for WC. The ones above are great budget spread players.
Not many WC OT around that Budget that I see that are great.
83 OVR KO Laremy Tunsil has been good for me - still using him.
OR
If you've got any Heavyweights, 82 OVR HW Russell Okung is decent and gives +1 IMB.
If no Heavyweights, 82 OVR RS Garett Bolles looks good and give your OGs +2 STR.
Base Trent Williams or Lane Johnson.
