Well, it would help if you would let us know what are your preferences. Are you female, or male, are you going to use it on a female or male? Do you have a color preference, what is the minimum or maximum width? How much insertable length do you need? Do you want, floppy, firm, velvety, very smooth? Would you want a vibrating option? Do you want a dildo that works very well without a harness? Do you know if the wearer's muscles are strong enough to hold it in, or will the harness actually be necessary?

You know... that type of stuff. Might actually give you an idea of what to think about when considering the purchase.
