In central Canada here, looking for a bench with the following:

-versatility for flat, incline, and decline exercises
-either comes with or can be connected with leg extension device
-rack, either connected or separate, that can double as a squat rack
-Optional but not necessary: preacher device connection

I am looking for solid and durable, something kids and adults can both use. Ideally, I would prefer a bench suited for an olympic barbell as opposed to smaller ones.

Any suggestions of brands / models I should consider? I would get second-hand but it might be difficult to track down in my area and shipping can be an issue.

Thanks.
