I've been thinking about copping one of these.How is the overall sound difference when using one.Maybe that's what people use with their portable turntables that I'm seeing alot of nowadays.I could never just sample straight from my handytrax and get a good sound,the needle just doesn't cut it anyways ,I've seen them range in prices from $30 to the hundreds and I know those are probabally for the audiophile type.Which kind will get the jobe done for basic sampling.
