Something that is affordable and made to use. It is not very fancy, not a showpiece, or work of art. Something that you can afford to get banged up. Usually a cue that will not really change in value much if it were played with or not.
Sometimes it may be a cue made by a reputable highly in demand cuemaker that is on the lower price range and usually a entry cue from their "catalog". It would be their basic no frill cue but still has their craftsmanship and methodology.
Now this is all subjective as it depends on your financial base on what you feel comfortable playing with.
